Ok this is a little info about upgrades and compatibility of 06' SFT parts to 07' NXT parts.

This info comes from one of the engineers at Smart Parts and the Manager of the Tech department at Smart Parts.

SFT vs. NXT Compatible Parts list.

INTERNAL PARTS:
All internals are exactly the same. This is everything from the solenoid, wiring harness, bolt guide to the orings. The one exception is the HE bolt is now stock in all NXT shockers. All manufacturers of HE bolts will work in both the SFT and the NXT as well as stock bolts from the SFT.

Q-LOCK:
SFT Q-lock will NOT work on the NXT.
NXT Q-lock will NOT work on the SFT.

There are completely new threads on the NXT. The thread is much larger (thicker) so it holds better. The NXT will have its own Feedneck and Smart Parts expects to have them out real quick. I’m sure other companies will do the same.

Grip Frame:
The SFT frame will work on the NXT.
The NXT frame will work on the SFT.

ASA:
The SFT ASAs will work on the new NXT body.
The NXT ASAs will NOT work on the SFT bodies.

TRIGGERS:
The SFT Triggers will NOT work on the NXT grip frame.
The NXT trigger will NOT work on the SFT grip frame.

BALL DETENTS:
SFT Ball detents will NOT work on the NXT.
NXT ball detents will NOT work on the SFT.

ELECTRONIC BOARDS:
They are explained in the letter below.

Shocker NXT Frequently Asked Questions:

Is this the ’07 Shocker? – No, this is the Shocker NXT. Our product development cycles at Smart Parts are not dictated by marketing schedules or calendars. We believe that equipment counts. Because of that, we want our customers to know that when they see the Smart Parts logo, they are getting the best value possible – more features, more reliability, and more performance per dollar. To do that, we release a new product when it is ready, rather than just cranking out a paintgun with a year label, cosmetic changes and incompatible parts designed to encourage players to buy a replacement marker every winter. The Shocker NXT was born out of feature requests from professional paintball players who depend on the Shocker, and from our service technicians who work with players at all levels of the game from pro to first timers. This information was fed to our design and engineering teams – some of whom are active tournament and or scenario players, and some who are able to bring a fresh perspective from unrelated industrial design experience. Various feature components hit the field in prototype and team gun production form for heavy abuse from our sponsored teams. When everything came together, proven and synchronized, the time came to unveil the Shocker NXT.

The Shocker NXT has breakbeam eyes – why does the manual mention reflective eyes? – Most maintenance and operation procedures in the Shocker NXT manual can be applied to the Shocker NXT, Shocker SFT (which uses reflective Vision) or private label Shockers with some NXT components. Players choosing to install an older aftermarket circuit board which does not support break-beam Vision will need to switch their Shocker NXT over to use reflective eyes.

Does the Shocker NXT use the Ion Regulator? – Almost, but not exactly. When we designed the Ion vertical regulator, we developed an efficient structure that provided a greater flow volume and better consistency than any of our previous vertical regulators. The Shocker NXT vertical regulator is built around the same design, with a spring spacer to allow for a slightly different pressure range, an integrated velocity locking screw for tournament legal operation and a friction washer that allows its body to include decorative milling that aligns with the Shocker NXT body.

What parts of the Shocker NXT are backwards compatible? – Most of the major systems – the vertical regulator, the body, the grip frame and the bolt assembly are interchangeable between the Shocker NXT and Shocker SFT, meaning that many aftermarket parts are plug-and-play ready for the Shocker NXT. Some specific combinations are worth noting:

· A newer, more rugged threading standard connects the Shocker NXT with its feedneck.

· The Shocker NXT body works with either reflective or break-beam Vision eyes, however break-beam eyes are not compatible with earlier Shocker SFT bodies.

· Shocker NXT and Blackheart circuit boards manufactured after August 2006 are compatible with break-beam or reflective Vision, earlier boards only support reflective eyes.

· The four-point adjustable Shocker NXT trigger is not compatible with the Shocker SFT grip frame. Similarly Shocker SFT and most aftermarket Shocker SFT triggers will not operate or adjust properly in the Shocker NXT grip frame.

· If the Shocker SFT vertical regulator is installed in an SFT vertical adapter combined with a Shocker NXT grip frame, the trigger guard may get in the way of the regulator’s hose fitting during assembly. Removing the trigger frame, installing the regulator, and then reinstalling the trigger frame will allow these components to be used together.

Why does the Shocker NXT use the same barrel threads as the Impulse and Ion? – The great thing about standards is that everyone has them. With this latest generation of the Shocker design, we saw the opportunity to unite all of the Smart Parts paintball markers with the same thread specification. The same barrels and Freak backs will work on the Shocker NXT, Nerve, Impulse, Ion and SP-8.

I have a problem and hope someone on here can help me out. My Shocker NXT eats a ton of air. I have a Virtue board and yes I have played with the dwell and many other settings. Is there a bolt that will make any difference at all? I play as a back and I can't run out of air on my fifth pod. At this point I have reverted back to my max'd ION. Any help would be great.

The NXT is already equipped with a high efficiency bolt kit that should be giving you something in the order of 1400 shots per fill (assuming a cold filled, full 68/4500).

You said that you had experimented with dwell, but how about operating pressure? You need to find the best balance between dwell and operating pressure. Takes a bit of time unfortunately.

Another thing to consider is the condition of your o-rings. May be worth getting a repair kit and totally overhauling the bolt kit.

There are aftermarket bolts and bolt kits available, as well as firing cans and other parts, but a lot of them are more concerned with reducing operating pressure rather than increasing efficiency. The Nox bolt might help a bit, but don't expect too much from it. The Eigen bolt hasn't been released yet, but testing appears to have shown positive results.

Another thing to remember is that a good bore to barrel fit will help with efficiency, as will barrel design (a lot of porting along a long section of the barrel, for example, will waste air).

Well thanks for the tip on barrels and such. I make sure the thing has a good seal and am very careful with my assembly. I actually Have turned the dwell up and lowered the pressure and turned it down and raised the pressure. I have never had this much problem with getting a marker dialed in. If I find the magic sweet spot. How many pods can I get from either a 72/45 high pressure or 68/45 low pressure?

Like I said, Smart Parts claim 1400+ shots from a 68/4500. That would equate to 1480+ from a 72/4500. That's 10 140 round pods from a 68/4500, or 8 and a half pods and a loader.

I love the way it shoots. I just need to find out how to get those numbers from it. One I get it dialed I never really mess with my markers. This is one that just seems to need alittle more love than the others I guess.
